Add LLDP reporting and validation to tripleo introspection/deployment

Registered by Dan Sneddon

Currently TripleO leverages Ironic-Inspector to do introspection on hardware nodes. Work is underway to add LLDP collection to ironic-python-agent. This data should be parsed and reported on in a human-readable form so that the operator can use this data for validation. The data may also be useful for automation in the future.

Whiteboard

The specification describes the work that will be done in ironic-inspector to parse the LLDP TLVs and store the data in swift. It also describes the changes to display the data in openstack commands via python-ironic-inspector-client. Additional work will be needed to use the LLDP data in tripleo validations to verify that the templates match the switch configurations. Some potential validations possible with LLDP data are:

- Verify VLAN IDs set on switch match VLANs in configuration in nic-config files
- Verify link aggregation is set on switch when bonds are configured
- Verify maximum frame set set is not less than mtu configured
- Verify that expected ports are configured for bonds
- Check that links are set to auto-negotiate
